Why is my crankshaft position sensor not working?

The trigger wheel located on the crankshaft or damper could have damaged or missing teeth. Any of these components could trigger a crankshaft position sensor to trouble code. Completing the above tests thoroughly will let you know if the crankshaft position sensor is working or not.

How to test the crankshaft position ( CKP ) sensor?

Now, since the crankshaft position (CKP) sensor can not be tested by a simple resistance test (multimeter in Ohms mode) off of the car, I’m gonna’ show you how to test it dynamically (in action) and on the car. This is a simple multimeter test done in Volts DC mode and I’ll walk you thru’ the whole thing step by step. Contents of this tutorial:

How is resistance tested on a crank sensor?

Only the 2 wire reluctor type crankshaft position sensor can be resistance tested. As you turn the key and crank the engine, each one of the three wires that connect to the crankshaft position sensor have a specific job to do: One delivers power in the form of 5 or 8 Volts from the PCM. This thru’ the wire labeled with the number 3.

Where are the teeth on a crankshaft sensor?

The trigger wheel located on the crankshaft or damper could have damaged or missing teeth. Any of these components could trigger a crankshaft position sensor to trouble code.

How can I test my crankshaft position sensor?

Here is how you can easily test both your crankshaft position sensor and camshaft position sensor. It’s very important to be able to test these sensor since because they control your ignition and fuel injector pulse and if they fail they could cause a Crank No start condition.

What is the number 1 on the crank sensor?

The number 1 is the signal wire that transmits the crankshaft position (CKP) sensor signal to the PCM. Connect the black multimeter test lead to a good Ground point on the engine or directly on the battery negative (-) terminal.

Is the camshaft sensor the same as the crankshaft sensor?

(Camshaft position sensors are the basically the same as crankshaft position sensors, but are easier to get to – ‘Murphy’s law’ dictates that out of the two, the crankshaft sensor is the one that will fail, because that is the harder of the two jobs to do!

How to change the crankshaft position of a car?

1. Set the parking brake and block the drive wheels. Make sure that the hood is closed. 2. Start the engine and make sure that the engine coolant temperature is at least 158 degrees F. (70 degrees C.) 3. Turn the engine off for at least 10 seconds. 4. Select the crankshaft position variation learn procedure (CASE Learn)on your scanner. 5.

The trigger wheel located on the crankshaft or damper could have damaged or missing teeth. Any of these components could trigger a crankshaft position sensor to trouble code.
